Title: Apparatus for injecting hot reducing gas into a shaft furnace
IPC: C21B5/00
Filed: 1975-03-20
Abstract: 1488976 Injecting reducing gas into a shaft furnace CENTRE DE RECHERCHES METALLURGIQUES - CENTRUM VOOR RESEARCH IN DE METALLURGIE 20 March 1975 [29 March 1974] 11733/75 Heading F4B [Also in Division H5] Apparatus for injecting hot reducing gas into a shaft furnace comprises a duct 4 that supplies reducing gas or a gas consisting of a mixture of hydrocarbon gas to be reformed and oxidizing gas to a tuyÞre 6 via an injection tube 5 that is coaxial with the tuyÞre. The injection tube is either wholly or only partly constituted by a plasma arc furnace enclosure 9, in which heat is supplied by a plasma arc generated by plasma arc torches 15. The injection tube may have two plasma arc furnaces in series with the reducing gas being produced by one plasma arc furnace and heated by the other. The plasma arc furnace enclosure 9 may have three radial plasma arc torches spaced at 120 degrees from one another with each torch connected to one phase of a three-phase electrical supply the neutral point of which is on the common longitudinal axis 10, 11 of the tube 5 and tuyÞre 6. The stability of the electric arcs may be assisted by adding compounds that can be easily ionized such as alkali metal or alkaline-earth metal compounds to the plasma generating gas.

Title: Improved apparatus for washing or separating ores
IPC: B03B5/62
Filed: 1922-04-28
Abstract: 189,399. Whitworth, M. April 28, 1922. Addition to 164,270. Inclined-trough washing-apparatus; jigs.-In the apparatus for separating ore from gangue described in the parent Specification, the perforated plate 10 and preferably the whole sluice box is inclined downwardly towards the feed end, that is in the reverse direction to the flow, and the perforations in the plate, are substantially at right-angles thereto, thus obviating the necessity of their being drilled at an angle to the vertical. The mixture of ore and gangue is fed with water down a slope 15, over the permanently secured end-plate 12, into the tank 4 having a perforated plate 10 covering the compartments 5 which are formed by the walls 6, the slope of the apparatus being adjusted by means of the framework 13. Water is supplied to each compartment 5 by means of the branch pipes 8 from a common supply pipe 7 connected to a variable head of water. The jets issuing through the perforations in the plate 10 raise the material and force it back, the heavier particles settling on the plate 10 as shown by the dotted lines 17, 18, 19, whilst the lighter particles are raised to the top and receive the full force of the flow of the stream and are carried forward and swept over the adjustable weir plate 14. When the heavies have accumulated to the position shown by line 19, the feeding of the material is stopped and the sluice, box emptied.

Abstract: 125,480. Automatic Telephone Manufacturing Co., and Smith, S. R. Aug. 26, 1916. Transmitters for hand signalling.-Signalling impulses of an audible frequency are generated by the operation of a key which, through gearing, causes a diaphragm to oscillate in front of the poles of a permanent magnet upon which a line coil is wound. In the arrangement shown, a diaphragm 39, Fig. 3, is mounted in front of the poles 40 of a magnet and is adapted to be engaged by a screw 30 mounted on a forked lever 29. The lower arm of the lever 29 is adapted to engage a toothed wheel 27, Figs. 1 and 3, under the action of a spring 31 when the lever 29 is allowed to rise by the operation of a lever 35 secured to a rocking shaft 33. The shaft 33 is rotated when the key 14, Figs. 3 and 4, is depressed by the engagement of a lever 22 with a lever 34, Figs. 1 and 4. The wheel 27 is rotated by the depression of the key 14 by causing an adjustable screw 15 on the key to engage a plunger 18 which is connected by a link 21 with the lever 22. A spring-controlled pawl 23 mounted on the lever 22 engages a wheel 24 secured to a shaft 6 which is geared by means of wheels 7, 8 to a shaft 9 carrying the wheel 27. A small fly-wheel 13 is also geared to the shaft 9, through wheels 10, 11.

Title: Improvements relating to the production of artificial silk
IPC: D01D10/04
Filed: 1932-05-02
Abstract: Artificial silk spinning-cakes or other bobbinless windings which have been treated with liquids and dried are wound off in such manner that the inner and middle thread layers which correspond to the approximately horizontal portion of the shrinkage curve are wound separately from the outer layers.  The thread obtained from the inner and middle layers shows very uniform shrinkage when subsequently wetted, and also dyes uniformly.  It is particularly suitable for use in the production of woven fabrics.  In some cases it shows a slight extension when wetted.  The non-uniform layers which may be wound-off first on to bobbins or into hanks are moistened and dried to improve their shrinkage properties.  The inner and middle layers are wound on to cross-wound bobbins, double flanged bobbins, cops, or other winding members.  The process is advantageously applied to spinning cakes which have been wet treated by the method of Specification 344,279.

Title: Improvements in or relating to the assembling of elastic articles in rigid apertures
Inventor: VINCENT RUSSELL SWALE
IPC: H05K13/00
Filed: 1950-05-22
Abstract: 682,859. Assembling rubber bush mountings. BRITISH DIELECTRIC RESEARCH, Ltd. May 21, 1951 [May 22, 1950], No. 12801/50. Class 108 (iii). A method of securing a body of insulating material having " elastic memory '' in an aperture in a rigid conducting member, the transverse dimensions of the body being greater than those of the aperture, consists in compressing the body to reduce its transverse dimensions to a value less than those of the aperture, and inserting it into the aperture after removing the forces of compression before the part inserted regains its original dimensions. Suitable materials for the method are polytetrafluorethylene, plasticized polyvinyl chloride, polychlortrifluorethylene, copolymers of tetrafluorethylene, ethylene vinyl chloride and chlortrifluorethylene with minor amounts of other polymerizable monomers, and mixtures of the polymers or copolymers with minor amounts of other materials. The materials must have a smooth surface of low frictional coefficient. The invention is described as applied to the insertion of a bushing 11, Fig. 2, of polytetrafluorethylene in a plate 22. The purpose of the bushing is to carry a conductor 23 within a central aperture which may be formed either before or after insertion of the bushing. The diameter of the aperture is <4>/5 of the initial diameter of the bushing. Compression of the bushing is effected within a tapered section 6, Fig. 1, of a bore formed in a barrel 1, under the action of a plunger 2. A non-tapered section 5 of the bore has a diameter equal to that of the bushing. This section may be made long enough to accommodate a number of bushings so that insertion may be effected successively. For bushings of 0.25 inch diameter, the diameter of the bore at the lower end of the section 5 is 0.003 inch less than that of the aperture. The bushings need not be cylindrical, and the crosssectional shape of the bore section 6 may vary from the top to the bottom. The bushings are formed by moulding polytetrafluorethylene powder with a compression ratio of 4 : 1, sintering at 350-380‹ C. for 20 minutes, and allowing to cool overnight in the oven. Another bushing described, was made from 65 parts of polyvinyl chloride and 35 parts of dioctyl phthalate. According to the Provisional Specification plasticized polystyrene, and copolymers of styrene, with minor amounts of other materials, may be used.
